CWE-184Published: July 21, 2026· Updated: Jul 21, 2026

9.9

CVSS v3.1

Official Description

PraisonAI is a multi-agent teams system. Prior to version 4.6.40 of PraisonAI, corresponding to version 1.6.40 of praisonaiagents, `execute_code()` in `praisonaiagents/tools/python_tools.py` (v1.6.37, subprocess sandbox mode) can be fully bypassed using `print.__self__` to retrieve the real Python `builtins` module, from which `__import__` can be extracted via `vars()` and runtime string construction. This achieves arbitrary OS command execution on the host, completely defeating the sandbox. This is a novel bypass that survives all patches for CVE-2026-39888 (frame traversal), CVE-2026-34938 (str subclass), and CVE-2026-40158 (`type.__getattribute__` trampoline). PraisonAI version 4.6.40 and praisonaiagents version 1.6.40 contain an updated fix.

Risk Analysis

The Python code execution sandbox in PraisonAI can be bypassed using built-in module access, leading to arbitrary OS command execution. This vulnerability completely defeats existing security controls and allows for full host compromise. The high CVSS score reflects the severity of this sandbox escape.

No public exploit is known, and it is not in the KEV catalog. The vulnerability is remotely exploitable.

Recommended Action

Upgrade to PraisonAI version 4.6.40 and praisonaiagents version 1.6.40 to receive the updated sandbox protection.

Technical Analysis

CVE-2026-47392 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.9.

The vulnerability has a "Changed" scope, meaning successful exploitation can impact components beyond the vulnerable component itself — such as the host operating system or adjacent services.
